问题描述
我想使用 JTable 的一些功能创建一个简单的表格,但更容易设置样式,所以我在框布局中创建了几个框,一个用于标题,另一个用于包含单元格。当我将 JScrollPane 添加到单元格的框时,它缩进了标题框,现在不对齐了。
未对齐的框:
我尝试过 setAlignmentX 和 ComponentOrientation,但运气不佳。有人有什么想法吗?
public class GUIInventory extends JPanel
{
Box headersBox = Box.createHorizontalBox();
Box cellsBox = Box.createVerticalBox();
JScrollPane scrollPane;
ArrayList<Box> rows = new ArrayList<>();
ArrayList<JLabel> cells = new ArrayList<>();
JLabel[] headerLabels = new JLabel[4];
String[] headerLabelNames = {"Name","Order Date","Order Number","Cost"};
public GUIInventory()
{
this.setBackground(Color.WHITE);
this.setLayout(new BoxLayout(this,BoxLayout.Y_AXIS));
this.setAlignmentX(Component.LEFT_ALIGNMENT);
Border outer = BorderFactory.createMatteBorder(0,1,Color.LIGHT_GRAY);
Border inner = BorderFactory.createEmptyBorder(10,10,10);
for(int i = 0; i < this.headerLabels.length; i++)
{
this.headerLabels[i] = new JLabel(this.headerLabelNames[i]);
this.headerLabels[i].setBorder(BorderFactory.createCompoundBorder(outer,inner));
this.headerLabels[i].setFont(new Font("Arial",Font.BOLD,16));
this.headerLabels[i].setMaximumSize(new Dimension(200,(int) this.headerLabels[i].getPreferredSize().getHeight()));
this.headerLabels[i].setAlignmentX(Component.LEFT_ALIGNMENT);
this.headersBox.add(this.headerLabels[i]);
}
this.headersBox.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createMatteBorder(1,Color.LIGHT_GRAY),BorderFactory.createMatteBorder(0,2,Color.BLACK)));
this.headersBox.setAlignmentX(Component.LEFT_ALIGNMENT);
this.headersBox.setBorder(BorderFactory.createLineBorder(Color.GREEN,2));
this.cellsBox.setBorder(BorderFactory.createMatteBorder(1,Color.LIGHT_GRAY));
this.cellsBox.setAlignmentX(Component.LEFT_ALIGNMENT);
this.scrollPane = new JScrollPane(this.cellsBox);
this.add(this.headersBox);
this.add(this.scrollPane);
}
